Vibrating feeder driven by three-phase vibration motor in metallurgical industry

With the development of my country's national economy, the metallurgical industry occupies an important position in the industrial field. Especially in recent years, the number of steel smelting enterprises has been increasing, and the improvement and innovation of steelmaking technology and equipment has attracted widespread attention. At present, the most commonly used iron and steel metallurgical equipment is the steelmaking electric furnace. Under normal circumstances, the steelmaking raw materials need to be fed into the furnace cavity through the charging car. The existing charging car uses a vibration motor as the excitation source when unloading the material to make the material follow The vibration of the loading box slides down into the electric furnace cavity through the discharge port.

The vibrating feeder is a new type of vehicle-mounted vibrating feeder developed according to the production needs of our country, based on digesting and absorbing the USK and USL type vibrating screens imported from German companies, and combined with my country's national conditions. It combines vibration conveying Design theory, and at the same time integrate the car with it. Through production practice, it is proved that this series of feeders have a series of improvements and improvements such as large processing capacity, reasonable technical parameters, high structural strength, high rigidity, stable and reliable operation, low noise, convenient maintenance and repair, perfect processing technology and manufacturing equipment, and a more reasonable structure , Higher quality. The feeder can be used for conveying and feeding materials in metallurgy, mining, building materials, chemical, electric power, transportation, casting and other industries.

An electric furnace vibrating charging vehicle includes a silo, a vibrating conveying trough, a bracket, and a traveling car body. The cross section of the silo is a trapezoidal trough structure. A vibrating conveying trough is installed at the lower part of the silo. The end is provided with a stainless steel blanking port, the brackets are located at the lower part of both sides of the silo, the vibration conveying trough and the silo are connected by rubber springs and brackets, and the vibrating conveying trough is set at the center of the side There is a vibrating motor, the trolley body is arranged on a ground track laid on a level ground, and the side of the trolley body is connected with a driving mechanism.

The vibrating conveying trough matches the shape of the silo, the cross section is a trapezoidal trough structure, and the size of the vibrating conveying trough is smaller than the silo. The vibration motor adopts a three-phase asynchronous vibration motor. The motor has a fully enclosed structure and can work without explosion-proof requirements. The product is small in size, light in weight, and the exciting force can be adjusted steplessly. It is convenient to use and maintain. By changing the installation method (and Horizontal angle) to change the direction of the exciting force and have a stable amplitude. There is also a drag chain system on the side of the traveling car body away from the blanking opening to protect the cables and other power lines from being uniformly fixed and prevent the power lines from being messy on site.

In the state of manual remote control, the walking trolley walks to the blanking position to feed the charging trolley during work, and then drives and controls the trolley to walk straight along the track to the electric furnace charging position to add charge. During the feeding process, the vibrating motor is turned on for uniform vibrating feeding of the electric furnace. The specific process is as follows: feed the material to the silo through the electromagnet above the feeder. After the filling is completed, go to the electric furnace. When the center of the feeding port and the center of the electric furnace overlap, stop moving forward (the position is adjusted for the first time, and the proximity switch is installed. Proximity switch controls the stroke), turn on the vibration motor for feeding, and reciprocate.
